IPC: G02F1/141
Filed: 2002-08-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide alignment of defect-free chiral liquid crystal giving a high contrast ratio to a liquid crystal display element by differentiating liquid crystal molecular alignment abilities of a pair of upper and lower liquid crystal molecular alignment layers which are disposed on the inner sides of upper and lower substrates in the liquid crystal display element using smectic liquid crystal, chiral smectic liquid crystal, ferroelectric liquid crystal, antiferroelectric liquid crystal and chiral nematic liquid crystal etc.  <P>SOLUTION: The liquid crystal molecular alignment abilities of the upper and lower alignment layers are differentiated as follow. (1) Alignment treatment methods of alignment films of the upper and lower substrates are differentiated. For instance, one side alignment film is subjected to optical alignment treatment and the other side alignment film is subjected to rubbing treatment or ion irradiation treatment. In such a case, the optical alignment gives the weakest alignment ability. On the other hand, the rubbing treatment etc. gives the strongest alignment ability. (2) Slightly strong polar molecules are attached to the alignment film of the side to be endowed with strong alignment ability and the wettability, that is, the adsorptive ability of the liquid crystal molecules is strengthened. (3) Chiral groups are attached to the alignment film of the side to be endowed with strong alignment ability or chiral molecules are added to the host liquid crystal and the substrate is allowed to assume chilarity of the same sign with the host liquid crystal.  <P>COPYRIGHT: (C)2004,JPO
